无法从L3Address调用inet函数

import socket

def get_network_address(ip_address):
    parts = ip_address.split('.')
    binary_parts = [format(int(part), '08b') for part in parts]
    network_address = ''.join(binary_parts)
    return network_address

ip_address = '192.168.0.1'
network_address = get_network_address(ip_address)
print(network_address)

import java.net.InetAddress;
import java.net.UnknownHostException;

public class NetworkAddressExample {
    public static void main(String[] args) {
        try {
            String ipAddress = "192.168.0.1";
            InetAddress inetAddress = InetAddress.getByName(ipAddress);
            byte[] addressBytes = inetAddress.getAddress();
            StringBuilder networkAddress = new StringBuilder();
            for (byte b : addressBytes) {
                networkAddress.append(String.format("%8s", Integer.toBinaryString(b & 0xFF)).replace(' ', '0'));
            }
            System.out.println(networkAddress.toString());
        } catch (UnknownHostException e) {
            e.printStackTrace();
        }
    }
}
